Definitions

  • the rotating spindle part contains a thread storage disk, on the outer circumference of which the thread radially guided out of the hollow spindle axis lies over a more or less large distance before it ballooning to a thread guide arranged in the extension of the spindle axis and continues to a take-off device or directly to a take-up unit.
  • the thread storage disk serves the purpose of taking up a certain thread reserve between the radial exit of the thread from the spindle and the balloon, which in turn ensures a constant thread tension and thus also ensures an even thread.
  • the thread storage by means of a thread storage disk can be referred to as an inertia-free thread brake.
  • Multi-wire twisting spindles without a thread storage disk generally require positive guidance of the thread balloon (US Pat. No. 2,127,921; US Pat. No. 2,609,652; German Pat. No. 1,268,031).
  • Such twisting spindles react very sensitively to changes in the inner thread tension (draw-off tension) or the outer thread tension (tension in the thread balloon), which often leads to thread breakage.
  • a forced thread guide in the area of the thread balloon can usually only be used for very tear-resistant yarns.
  • CH-PS 417 418 mentions a balloon limiter which rotates with the rotor of the twisting spindle as a storage disc replacement.
  • the storage on the inner jacket of a rotating balloon limiter can be thought of as a space curve of the thread (slight spiral shape).
  • the balloon thread remains in the gap between the bobbin holder or bobbin protection pot, which may also rotate counter to the spindle rotor and balloon limiter, that is, the thread is braked.
  • the space curve of the thread begins at the outlet opening from the spindle rotor and ends at the transition from the highest point of contact on the balloon limiter to a balloon thread guide eyelet located in the spindle cover, or directly in the balloon thread guide eyelet for spindles without a spindle cover.
  • the balloon thread When the spindle starts up, the balloon thread hits a standing column of air, which results in its lagging behind the rotating balloon limiter.
  • the space curve of the thread balloon extends over a certain circumference of the spindle with the possible consequence that the balloon thread can wind spirally around the outer circumference of the counter-rotating bobbin. As a result of the rope friction, the balloon thread would be pinched off, resulting in a thread break leads.
  • the thread guide eyelet is attached to the upper edge area of the balloon limiter which is just touched by the thread.
  • the thread guide eyelet is equipped with an elongated opening in the circumferential direction of the balloon limiter inner jacket, which allows the thread to swing freely within this length. This is always the case when the thread balloon has to adapt to these changes in tension as a result of changed internal or external thread tensions.
  • the thread or thread balloon can swing in the frame of the elongated thread guide eyelet according to the required tension adjustment.
  • the circumferential length of the thread guide eyelet should be about +/- 15 ° in all working positions set angular position of the thread guide eyelet position.
  • the thread guide eyelet is preferably designed so that the thread is automatically threaded into the thread guide eyelet depending on the direction of rotation of the spindle. To take account of opposite spindle running directions, two diametrically opposite thread guide eyes are provided on the circumference of the balloon limiter. The balancing state of the rotating balloon limiter is maintained at the same time.
  • the thread guide eyes are attached to the balloon limiter so that they can be adjusted between 20 o and 120 o relative to the radial exit of the thread from the spindle rotor.
  • a portion of the balloon limiter can be rotated relative to the radial outlet of the thread on the spindle rotor in order to achieve the desired angular distance ⁇ .
  • the aim of the invention of a reliable thread storage in the thread balloon is only achieved if it is ensured that the thread does not tend to wrap around the bobbin by, without positive guidance of the thread by a certain angular distance to the radial exit of the thread from the spindle rotor on upper balloon limiter attached thread guide eye thread storage is achieved.
  • Figure 1 shows, representative of a twisting machine, part of a spindle bench 1, in which a spindle bearing sleeve 2 is mounted in a stationary manner.
  • a spindle shaft 5 is rotatably mounted in the spindle bearing sleeve 2 by means of bearings 3 and 4, on the lower end of which a spindle whorl 6 which can be driven in the direction of arrow f1 is fastened.
  • the spindle hollow axis 7 At the upper end of the spindle shaft 5 there is the spindle hollow axis 7, at the lower end of which a turntable 8 provided with a radial thread guide channel 9 is fastened.
  • the turntable 8 is surrounded by a ring 10 which has a deflecting duct 11 which adjoins the thread guiding duct and runs first radially and then axially upwards.
  • a balloon limiter 12 Connected to the ring 10 is an upwardly extending balloon limiter 12, which in its upper region, preferably at the upper balloon limiter edge, carries a thread guide eyelet 13 at an angular distance from the radial outlet opening of the thread guide channel 9.
  • An annular body 14 adjoins the lower edge of the balloon limiter 12 essentially in the manner of a flange.
  • a thread deflecting body 15 is inserted, which has a thread deflecting channel 16 with an axial channel section and a radial channel section opening into the thread guiding channel.
  • a coil carrier shaft 17 which can be driven in the opposite direction to the spindle shaft 6 in the direction of the arrow f2 is rotatably mounted.
  • entraining magnets 18 are inserted along a circular path, which are below the Protect the turntable 8 in an annular space.
  • a sleeve-shaped coil carrier hub 21 is rotatably mounted by means of bearings 19 and 20, which has, for example, a stepped coil carrier base 22 at its lower end, which carries a coil carrier protective pot 25 on its outer circumference.
  • counter magnets 18.1 are fastened opposite the driver magnets 18, which, relative to the driver magnets 18, are polarized in such a way that when the coil carrier whorl 17 rotates, the coil carrier consisting of coil carrier hub 21, coil carrier base 22 and protective pot 25 is also inserted driven in the same direction.
  • a thread inlet tube 23 is inserted concentrically to the hollow spindle axis 7.
  • a supply spool 24 is pushed onto the spool support hub 21 and placed on the stepped spool support base 22 in such a way that the supply spool 24 is also set in rotation without slippage when the spool support 21, 22 is rotating.
  • the thread F is pulled upwards from the supply spool 24 and first downwards through the thread inlet tube 23 and the spindle hollow axis 7 and then radially outwards through the radial thread guide channel 9 and then again between the bobbin protection pot 25 and the balloon limiter 12 a thread guide eyelet 26 (FIG. 2) lying in the extension of the hollow spindle axis, from where the thread then runs to a winding unit (not shown).
  • the thread is passed through the thread guide eyelet 13, which lies at a suitable angular distance from the outlet opening of the radially directed thread guide channel 9 or the thread deflecting channel 11.
  • Two diametrically opposite thread guide eyes 13 are preferably provided in order to avoid unbalance and to ensure a smooth running of the rotating balloon limiter.
  • the presence of two diametrically opposed thread guides also enables the procedure according to the invention in both directions of rotation of the balloon limiter 12 on the one hand or of the bobbin holder represented in FIG. 2 by the bobbin holder pot 25.
  • the thread guide eyelet 13 is preferably at an angle ⁇ between 20 ° and 120 ° at a distance from the outlet opening of the thread deflection channel 11.
  • the mentioned angular distance is represented by the angle ⁇ , namely based on the axial plane defined by the x coordinate, in which the thread deflection channel 11 lies, on the one hand and the passage point of the thread 11 through the thread guide eyelet 13 on the other hand.
  • the thread guide eyelet 13 has an elongated shape in the circumferential direction of the balloon limiter 12, which allows the thread F to oscillate freely within this opening length, so that the thread balloon can adapt to the yarn and run-dependent thread tensions.
  • the yarn guide eyelet 13 has in the circumferential direction preferably have a circumferential length corresponding to +/- 15 o to the central or middle position of the yarn guide eyelet 13 angle relative to Fadenumlenkkanal. 11
  • the diametrically opposite thread guide eyes 13 are attached to the upper edge of the balloon limiter 12 in an unadjustable manner.
  • provision can be made according to the invention to adjust or twist the balloon limiter 12 or at least a portion of the balloon limiter relative to the thread deflecting channel 11.
  • Figure 2 indicates or shows that if there is no thread guide eyelet 13 on the upper, co-rotating edge of the balloon limiter 12, an unwanted wrap of the thread around the inner bobbin 25 could very quickly take place, which, as already mentioned above, would result in a thread breakage due to the rope friction effect would lead.
  • Figure 3 shows an embodiment of a hand threadable eyelet 13 in the form of a bracket 27 which is resiliently clamped in the balloon limiter 12 by means of an elastically deformable holder 50.
  • the free, beak-shaped bow end can therefore enter an opening 12.1 made in the balloon limiter 12 as a result of the centrifugal force.
  • a closed thread guide eyelet 13 is formed, which prevents the thread from being pulled out of the thread guide eyelet 13 even when the thread F oscillates in the circumferential direction between the extreme positions F1 and F2.
  • FIGS. 4 to 6 show a likewise elongate thread guide eyelet 113 which is adjustable in the direction of the double arrow f3 relative to the balloon limiter 12 and is attached to a clamping body 114 which can be clamped in various positions on the upper balloon limiter edge.
  • the balloon limiter can, for example, have locking openings 12.2 as locking elements for clamping lugs 114.1 attached to the clamping body 114.
  • the thread guide eyelet 113 is formed by a bow-shaped ceramic body 115, which can be elastically fastened to the clamping body 114 with one end in accordance with the embodiment of FIG. 3, while the other end can be, for example, beak-shaped and to form a closed eyelet with an opposite, preferably also beak-shaped counter element 116 cooperates overlapping.
  • At least the parts of the thread guide eyelets 13, 113 and 213 which are covered by the thread consist of a wear-resistant material or have a coating of wear-resistant material.
  • FIGS. 7 to 9 show an automatically elongated thread guide eyelet 213 in the form of a bracket 215, which automatically opens when the spindle is at a standstill, and which is pivotably pivoted about the pivot axis 214 on a carrier body 216 which is fastened to the upper edge of the balloon limiter 12 in the direction of the double arrow f3 .
  • a spring element 217 which is supported on the carrier body 216 and by which the bracket 215 is pivoted or pressed into the open position shown in FIG. 7, can act on the bracket end located in the region of the pivot axis 214.
  • this bracket 215 is moved by centrifugal force into the closed position shown in FIG. 8 in order to form a closed thread guide eyelet 213 for the thread F.
